No of molecules in 0.5 mole of H2O = no of moles * avogadro's number
                                                           = 0.5 * 6.022 * 10^23
                                                           = 3.011 * 10^23 molecules
Therefore, no of H^+ ions in H2O = 2 * 3.011 * 10^23
                                                       = 6.011 * 10^23 
Same process can be followed  in part (2).
Hope this helped you!!!!!!!!!!!!!!!!!!!!!!!!!
